Description
л ет 0,025-0,05 об. %. Предложенный способ дает возможность определ ть содержание влаги с точностью +5% в интервале от 0,025 до 5%.l et 0.025-0.05 about. % The proposed method makes it possible to determine the moisture content with an accuracy of + 5% in the range from 0.025 to 5%.
Пример. К 2 лл анализируемого органического вещества добавл ют 3 мл люминесцирующего раствора нитрата берилли с салициловым альдегидом и довод т до 100 мл осушенным ацетоном. Интен сивность измер ют через 1 час на флуориметре при 366 млгк нри 20° С и сравнивают с контрольным опытом. В контрольном опыте используют раствор, состо щий из 2 мл осущеиной исследуемой жидкости и 3 мл люминесцирующего раствора .Example. To 2 liters of the analyzed organic matter is added 3 ml of a luminescent solution of beryllium nitrate with salicylic aldehyde and brought to 100 ml with dried acetone. The intensity is measured after 1 hour on a fluorimeter at 366 mlgc at 20 ° C and compared with the control experiment. In the control experiment, a solution consisting of 2 ml of osuschein test liquid and 3 ml of a luminescent solution is used.
При определении влаги в сол х соли растирают , воду экстрагируют ацетоном н провод т определение, как описано выше.When determining the moisture in the salts, the salts are triturated, the water is extracted with acetone, and the determination is carried out as described above.
Предмет изобретени Subject invention
Способ определени влаги в веществах по гашению люминесценции оптически активного вещества, отличающийс тем, что, с целью повыщени точности определени и увеличени числа анализируемых соединений, в качестве оптически активного вещества используют комплексное соединение нитрата берилли с салициловым альдегидом в осушенном ацетоне .The method of determining the moisture in substances for quenching the luminescence of an optically active substance, characterized in that, in order to increase the accuracy of determination and increase the number of analyzed compounds, the complex compound of beryllium with salicylic aldehyde in dried acetone is used as an optically active substance.
